From the Devs
Glass doesn't crack here. It detonates.
The Prism Vaults have been growing inward for centuries. Two hundred chambers of corrupted crystal, stacked into eight acts, and one way through: the
AEGIS, a phase shield riding a magnetic rail, and the
Photonic Core you send into the formation. What comes back depends on where you hit it. There are no fake bounces:
the contact point decides the angle, and learning to read it is the whole game.
The wall comes down. You decide what it costs to push it back.
Every few seconds the formation drops one step. Whether you're breaking crystal or not. The only thing that lifts it is
REFLUX, and REFLUX is paid in
PRISM: the energy crystals release when you chain past the maximum multiplier. You have three ways to spend that reserve, and two of them never fit at once:
- REFLUX — lifts the wall one step and buys you the full timer back.
- FLARE — cashes the entire reserve in points. It pays more the higher the wall sits… which is exactly what forces you to spend on REFLUX. That's the decision, and it's tight on purpose.
- WILDCARDS — the only spend that keeps. POWER hands you a power-up on the spot; EASY SCREEN rewrites the screen you're on, in exchange for paying less.
Five kinds of crystal that fight back
The
Lattice shatters. The
Bulwark takes three hits and cracks open as it goes. The
Anchor never breaks: use it as a wall or play around it. The
Volt Cell detonates and takes its neighbours with it. And the
Drift Vane moves while you're aiming.
Five elements, one cannon, and the reactions between them
Ember, Cryo, Lithic, Tidal and Vortex. Each loads the AEGIS cannon with its own ammunition and its own destruction geometry; each leaves a mark on the crystal it touches, and another element on that mark
reacts. Vortex also pulls everything falling toward you and bends the core toward the crystal. Add Expand, Magnetic Anchor, Bulwark Field, Fission ×2 and ×3, Pierce and Calm: twelve pickups, and not one of them is "more of the same".
Eight acts that don't sound alike
Antechamber, Foundry, Garden, Bazaar, Dunes, Current, Corona and Core. Every act has its own light, its own echo and its own music. In the Garden, the rhythm blooms in 3+3+2; in the Dunes, time stretches out beneath the haze; in the Core, the heartbeat turns urgent and unstable. Each of the 8 acts holds a melody of its own:
eight recorded pieces, one per act, plus the two title themes and the victory piece.
Forty sectors, and gates to skip them
40 sectors × 5 screens = 200. From Act II on, finishing the second sector of each act opens a
branch gate: spend a core — never your last — and skip the whole next sector, five screens, PRISM intact and a bonus waiting on the other side. And from Act II on, 33 screens — always the middle one of their sector — carry an
optional challenge — Time Trial, Few Launches, Never Lose the Core, Hunt — that pays extra and never punishes.
Everything is reproducible
Every screen is generated from a fixed seed: identical in every run and on every machine. Nothing is random, so you can memorise a screen and replay the line. And the
daily run is the same for everyone that day, with its own table.
Three difficulties that genuinely play differently
Relaxed,
Standard and
Expert change cores, shield resilience, top speed, drop rate, assistance and scoring. It is not one damage multiplier wearing three names. And all 200 screens are
proven completable on all three — not assumed.
Built not to let you down
- Thirteen languages, the whole interface, not just the menus.
- Keyboard, mouse, touch and gamepad, all four tested.
- Real accessibility: high contrast, damage marked by pattern and not colour alone, reduced motion and reduced flashing, adjustable shake, interface scaling and separate volumes.
- Your save survives: versioned saves that migrate themselves and quarantine a corrupted file instead of swallowing it.
- If the game decides something for you, it says so. If it lowers the frame cap because it found an integrated GPU, you get a notice. It never degrades quietly.
The technical part, without the smoke
Rendered with
WebGPU, with automatic fallback to WebGL2. On integrated graphics the game applies the 60 FPS cap by itself — measured: with the factory cap it dropped between 27 and 129 frames per thirty-second window; with the 60 cap,
not one — and it changes not a single pixel of the image to do it. Every other power-saving setting sits behind a button you press yourself, with "Factory settings" next to it to undo the lot.
